我对宝石有严重的问题。它在rails控制台中工作得非常好，但在lib/It中不是

非常抱歉，问题出在tweet_文本中-它不能有特殊符号。我希望有一天这能帮助别人。。。我花了4个小时。

这里没有对每个_字节的引用，所以您可能需要进一步挖掘。@tadman这是日志中每个_字节的唯一引用=cmd+f，只出现在错误消息中。它在第308行的rfc2396_parser.rb文件中。@tadman补充了这个问题

  def escape(str, unsafe = @regexp[:UNSAFE])
  unless unsafe.kind_of?(Regexp)
    # perhaps unsafe is String object
    unsafe = Regexp.new("[#{Regexp.quote(unsafe)}]", false)
  end
  str.gsub(unsafe) do
    us = $&
    tmp = ''
    us.each_byte do |uc|
      tmp << sprintf('%%%02X', uc)
    end
    tmp
  end.force_encoding(Encoding::US_ASCII)
end
